Beschreibung
Zusammenfassung:	The present invention relates to a sound absorbing and insulating material with improved heat resistance and moldability and a method for manufacturing the same, more particularly to a sound absorbing and insulating material having, as a surface layer, a heat-resistant material prepared by impregnating a binder into a nonwoven fabric formed of a heat-resistant fiber stacked on one side of a base layer formed of a conventional sound absorbing and insulating material, and a method for manufacturing the same. The sound absorbing and insulating material of the present invention is a conventional sound absorbing and insulating material has improved sound-absorbing property, flame retardancy, heat-insulating property and heat resistance as compared to the conventional sound absorbing and insulating material, is applicable to parts maintained at high temperatures of 200 °C or higher due to the surface layer and is moldable into a desired shape during the curing of the binder impregnated into the surface layer. Therefore, the sound absorbing and insulating material of the present invention can be widely used in industrial fields requiring sound absorbing and insulating materials, including electric appliances such as an air conditioner, a refrigerator, a washing machine, a lawn mower and the like, transportation such as an automobile, a ship, an airplane and the like, construction materials such as a wall material, a flooring material and the like, and so forth.
